Answer:

y=-5/2x-1

Step-by-step explanation:

y-y1=m(x-x1)

y-9=-5/2(x-(-4))

y-9=-5/2(x+4)

y-9=-5/2x-20/2

y-9=-5/2x-10

y=-5/2x-10+9

y=-5/2x-1

Answer:

$p =2.15n - 875$

Step-by-step explanation:

Given

$CD_s= n$

$Charges = 2.50$ per CD

<u>Expenses</u>

$E_1 = 875$

$E_2 = 0.35$ per CD

Required

The profit (p)

First, calculate the total income on n CDs

$Total = Charges * n$

$Total = 2.50 * n$

$Total = 2.50n$

Next, the expenses on n CDs

$Expenses = E_1 + E_2 * n$

$Expenses = 875 + 0.35 * n$

$Expenses = 875 + 0.35n$

The profit (p) is:

$p = Total - Expenses$

$p =2.50n - (875 + 0.35n)$

Open bracket

$p =2.50n - 875 - 0.35n$

Collect like terms

$p =2.50n - 0.35n - 875$

$p =2.15n - 875$

How is the process of finding equivalent ratios like the process of finding equivalent fractions

max2010maxim [7]

It is the same process because ratios and fractions are the same. For example, ratio 1 : 3 can be written in the form of fractions as 1/3. Ratio 1 : 4 is fraction 1/4, and so on. So, if you want to find equivalent ratios, you will use the same process as for finding equivalent fractions.

What is the slope and y-intercept of the graph of the equation?

belka [17]

Answer:

Slope = -4/3

y intercept = 4

Step-by-step explanation:

Change the equation given into slope intercept form

3y + 4x = 12

3y = -4x + 12

y = -4/3 + 12/3

y = -4/3 + 4

m = -4/3 b = 4
